Abstract:

The assembled 3D and 4D computer models of T-x-y and T-x-y-z diagrams permit to verify and validate the data on phase equilibria and to design the microstructures of heterogeneous material, including the materials genome decoding. “Phase Diagram (PD) as a Tool of Materials Science”, http://ipms.bscnet.ru/labs/skkm.html , is focused on the following topics: concentration fields of different dimension with the different solidification schemes and microstructures, correction of PD graphics, multi-component systems polyhedration, 3- and 4-phase regions with the reaction type changing, competition of crystals with different dispersion in the invariant regrouping of masses, mathematical approximation of PD, assembling of PD computer models, 3D prototyping of the phase regions and concentration simplexes for the exploded PD and for the concentration complexes of the reciprocal quaternary systems, simulation of DTA spectra and X-ray analysis spectra in the training programs for specialists in the field of physics-chemical analysis. Computer models of PD are the wonderful addition for the thermodynamicaly assessed experimental PD.
